I have been trying to crack WPA using aircrack-ng dictionary based attack. I have a huge word list and I'd like to know if there is a way to start from bottom of the wordlist, like starting with last word in file to the first. Is there any tool or technique that will let me create a copy of the same dictionary but in reverse order.(And I do own the access point I am trying to gain access into. This question is just out of curiosity because I couldn't finish entire dictionary in one go, it stopped at around 90%, it'd be better to start from bottom).

Thanks for all the answers.Tac worked like charm!!I ended up writing a small python script that could invert the word list. 'split' does a good job in breaking down a large dictionary into small chunks.
